For interactive content, Selenium’s Java integration allows me to navigate JTB’s booking options and capture live pricing details.

• By setting up regular scrapes, I monitor how prices fluctuate across popular destinations, like Tokyo or Kyoto, based on seasonal demand.

To scrape travel deals from JTB Japan using Java, you can use the popular Jsoup library, which simplifies HTML parsing and web scraping in Java. Below is a basic example of how to scrape the data from a webpage (in this case, JTB Japan), keeping in mind that you need to comply with their robots.txt and any legal guidelines when scraping.
Prerequisites:

1. Add Jsoup dependency to your project. If you’re using Maven, add the following to your `pom.xml`

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.15.3</version>  <!-- Make sure to check for the latest version -->
</dependency>

2. You will need to adjust the URL and HTML parsing logic according to the actual structure of the JTB Japan webpage and the specific travel deals you want to scrape.

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import java.io.IOException;
public class JTBTravelDealsScraper {
    public static void main(String[] args) {
        // URL of the JTB Japan travel deals page
        String url = "https://www.jtb.co.jp/travel-deals";  // Replace with actual URL of deals
        try {
            // Connect to the URL and fetch the HTML document
            Document doc = Jsoup.connect(url).get();
            // Example: Scraping travel deal titles, assuming they are in <h2> tags with class "deal-title"
            Elements dealTitles = doc.select("h2.deal-title");  // Update the selector based on actual HTML
            System.out.println("Travel Deals from JTB Japan:");
            // Loop through and print the travel deal titles
            for (Element title : dealTitles) {
                System.out.println("Deal: " + title.text());
            }
            // Optionally, you could scrape more info like prices or URLs:
            Elements dealLinks = doc.select("a.deal-link"); // Update this selector accordingly
            for (Element link : dealLinks) {
                String dealUrl = link.attr("href");
                System.out.println("More Info: " + dealUrl);
            }
        } catch (IOException e) {
            System.out.println("Error connecting to the page: " + e.getMessage());
        }
    }
}

• Jsoup: A Java library used to parse HTML and extract data from web pages.
• URL: Replace the `url` variable with the actual URL of the JTB Japan travel deals page.
• Selectors: You’ll need to inspect the page source (using browser developer tools) to find the correct CSS selectors for the elements you want to scrape, such as titles, prices, and URLs.
• Error Handling: The `IOException` is caught to handle issues like network errors or invalid URLs.

• Parsing JSON responses in Java enables faster data extraction if travel package details are available via AJAX.

• I use Java’s ScheduledExecutorService to automate scrapes, capturing travel deals at different times and comparing day-to-day price changes.
